It appears that T-Mobile is staying true to its word when it comes the Android 2.2 update for the Samsung Vibrant - the much-anticipated software upgrade is now slowly but surely rolling out.

There's a catch, though: it's only available through Samsung's Kies Mini software (which runs exclusively on Windows - sorry, OS X users). We aren't yet sure if/when an OTA update will accompany this Kies Mini version, but here's what we do know: the update's build number is UVKA6, and it contains T-Mobile TV and WiFi calling in addition to all the usual Froyo goodies.

Update: T-Mobile confirmed that the update rollout has begun and posted upgrade instructions together with a handy FAQ right here. They've also confirmed that the update will be delivered exclusively via Kies and will not be available OTA (over-the-air).

Granted, it's been almost exactly eight months since Froyo was announced (and over a month since European Galaxy S devices received the update), but I suppose it's better late than never. Let's just hope Verizon, AT&T, and Sprint follow suit before too long!
